In reviving this place for the Spring/Summer (dare I dream even more?) I wanna remember that the name is "Adventures with Fish", not just fishing, and with that in mind here's a great start to a new series on Discus keeping by a man who knows them better than most of us ever will.
With Practical Fishkeeping, Heiko Bleher is presenting a series on Discus that judging by part one, will be a superb in-depth look at one of my favorite fish! Here's a sample:
All three species of Discus can easily be distinguished by their own chemical water parameters and that’s why I recommend never keeping them together.The habitat of Heckel Discus (S. discus) is always water of a dark tea colour, with visibility up to 1m/3.3’ and rarely more; pH never above 5.0 but averaging 4.5; conductivity from 6-12 µS/cm — but the average is always below 10. They live only in extreme acid water and oxygen concentration is often only 2.8 mg/l.
Heckels are active in daytime in groups of 30-200 or even more, standing in deep water, along rivers, or lake edges at a drop-off, normally at a depth of 1.5-4m/5-13’ among mostly acará-açú bushes (Licania spp.), a plant widespread in the Amazon basin and living partly under water.
In between are fallen trees and logs — and there’s always fine white sand present too.
Check it out, it's a great introduction that has me already looking forward to the rest of the series!
